In the summer of 1951 the health of King George VI entered into a serious decline, and Princess Elizabeth represented him at the Trooping the Colour and on various other state occasions. On October 7 she and her husband set out on a highly successful tour of Canada and Washington, D.C. After Christmas in England she and the duke set out in January 1952 for a tour of Australia and New Zealand, but en route, at Sagana, Kenya, news reached them of the king's death on February 6, 1952. Elizabeth, now queen, at once flew back to England. The first three months of her reign, the period of full mourning for her father, were passed in comparative seclusion. But in the summer, after she had moved from Clarence House to Buckingham Palace, she undertook the routine duties of the sovereign and carried out her first state opening of Parliament on November 4, 1952. Her coronation was held at Westminster Abbey on June 2, 1953
